Abstract (en)
[origin: WO2019130234A1] A retroreflective article comprises (a) a retroreflective layer including a structured surface that is opposite a major surface, (b) a pressure sensitive adhesive that contacts at least a portion of the structured surface to form an optically inactive area that does not substantially retroreflect incident light and (c) at least one low refractive index layer forming an optically active area that retroreflects incident light; wherein the optically active area comprises about 25% or less of the structured surface.
